This corporate tax issue has been at the center of congressional debate on tax reform. Some lawmakers have advocated getting rid of offshore deferral, and others have pushed for a "tax holiday" that would allow these corporations to bring foreign profits back into the United States at a low tax rate. Democratic Senator Max Baucus, former finance committee chairman, had made a number of tax reform proposals before leaving to become ambassador to China. Senator Ron Wyden has taken over Baucus' post.

Analysts do not anticipate any real reform action until after the mid-term elections in November, but Americans can expect to see a push for a tax code overhaul in 2015.
